As rt_iif represents input device even for packets coming from loopback with output route, it is not an unique key specific to input routes. Now rt_route_iif has such role, it was fl.iif in 2.6.38, so better to change the checks at some places to save CPU cycles and to restore 2.6.38 semantics. compare_keys: - input routes: only rt_route_iif matters, rt_iif is same - output routes: only rt_oif matters, rt_iif is not used for matching in __ip_route_output_key - now we are back to 2.6.38 state ip_route_input_common: - matching rt_route_iif implies input route - compared to 2.6.38 we eliminated one rth->fl.oif check because it was not needed even for 2.6.38 compare_hash_inputs: Only the change here is not an optimization, it has effect only for output routes. I assume I'm restoring the original intention to ignore oif, it was using fl.iif - now we are back to 2.6.38 state Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S.
